You Must Register to Download LightZone

Update: Effective March, 2014, you must be a fully registered member of The LightZone Project in order to download the program. See the message above about registration. Once the registration process is fully completed and you have logged in after approval, you will see the download links for Linux, Windows, and Mac in the left sidebar. Approval is now automatic. Refresh your browser if you do not see the links. Contact us if you have further problems, but please follow the instructions in "contact". The program remains free of charge. We are requiring membership for security purposes, to better track the downloads, and to help build the community in order to attract developers and improve the knowledge base. It is fine if you do not wish to participate in the forums---no one is forcing you to---- but we would like you to participate and believe that in the long run a larger member base will be better for the project, especially in terms of attracting development support. We do not think it is too much to ask that you register in exchange for free and quite interesting software. We hope that you like it as much as we do, and will share with the community your experiences, questions, and comments.

Happy Birthday to Us!

Posting rules: It shouldn't need saying, but... play nice. Please keep your discussions civil. You can disagree, just don't be disagreeable. And, of course, all of the usual stuff like no spamming. Tex adds: I'll be rigorously enforcing this as we go along. We're probably going to be a small community in a little lifeboat, so we can't have members at each others' throats. This is for the sake of the project as a whole. So when you post, pretend you're speaking in person with your very wealthy auntie who has always treated you wonderfully and currently lists you prominently in her will. I won't be tossing anyone out of the forums because we are all in this together (except spammers: immediate membership cancelation), but I'll delete suspect posts right away.

Four years ago today, tex and I took the LightZombie.org web site live.

Three years ago today, Anton Kast joined the project and soon began negotiations that led to the release of the LightZone source code under the BSD open source license. At the time, we had between 200-250 registered members. Today, we have over 97,000 registered members, and should be crossing the 100,000 mark in the next few months.

If you're curious, here are a couple of postings that give a quick look at the early history of the project:

It's been a great journey, and we thank you all. Special thanks to Pavel Benak (Aries85) and his team who took the commercial LightZone 3.9 and remolded it to fit the open source world as LightZone 4.0, along with additional language translations from a number of contributors, and to Masahiro Kitagawa (ktgw0316), who's been our lead developer on the improvements in LightZone 4.1.

This has been and remains a pretty amazing sequence of events, and for me it's hard to believe it's been 4 years. To everyone who has helped on the development side, once again we can't thank you enough. To those who helped with long hours to get us started and sorted, a huge thanks. To Masahiro Kitagawa, it was wonderful to meet you (and Aya!) last month, and we owe you an incredible debt of thanks for sticking with the project this long. To Doug---thank you for all you have done in the beginning, the middle (long after you had said you would stop), and now for coming back in in recent weeks to help with the spammers again. And all this during a bumpy time for you (and I empathize, having endured that myself...).

And to all our forum contributors, who do daily work with technical support, thanks to you! We are a vital community because of everyone. So, Happy Birthday to us.
